DISMOUNTABLE COVERING AND COVERING CONSTRUCTION METHOD Russian patent published in 2001 - IPC

FIELD: agriculture. SUBSTANCE: dismountable covering has carcass composed of pair of base passes 3 and 4 and apex pass 5 which are laterally connected along carcass length through transverse members 6, and flexible strip 7 positioned over carcass. Carcass base passes 3 and 4 are attached to flexible strip 7, and apex pass 5 is resiliently biased to flexible strip 7 through transverse members 6 mounted between passes. Each transverse member 6 has length changeable under load, with length of unloaded member 6 exceeding half the distance between base passes, when they are expanded to maximum extent. To mount covering, it is sufficient to mount transverse members 6 on base passes 3 and 4 attached to flexible strip 7 and on apex pass 5, with following moving of apex pass 5 toward flexible strip 7 for bending carcass to opposite side and for tightening strip 7. EFFECT: simplified construction, easy assembly and disassembly and convenient operation. 34 cl, 32 dwg
